Performance enhancements

The regular expression engine has been completely rewritten to make it significantly faster. Tests indicate simple regex is at least three times as fast as the earlier regular expression engine, and 10 times or more faster for more complex regular expressions. In addition, constant regular expressions are now compiled when the containing procedure is compiled to eliminate the runtime cost of regular expression compilation and to detect errors in regular expressions at SOUL compile-time lather than evaluation time.
